Wisconsin has slightly different axle weights permitted on tandem axles, with slightly more permissive weights allowed. Twin trailers are not allowed off of designated highways, and a towbar length of 12’ is specified. There is a kingpin to center of tandems distance of 43’ specified in Wisconsin, which is longer than most other states that do have a length specified. Non-designated highways have weight reductions of 60%. True to the stereotype, Wisconsin has lots of exemptions for dairy haulers.
